The styles are actually stored in the database, so deleting the folder won't completely remove them.

If you're worried that the stock styles really aren't correct, then what you can do is import the stock ones. When you grab the 7.4.1 zip, inside the install directory is a styles directory. You can import the 2 files in there and that will give you the 2 styles that come with the release.
